IN A TEN-MINUTE interview aired Wednesday morning, NPR’s David Greene asked Wikileaks founder Julian Assange five times to reveal the sources of the leaked information he has published on the internet. Greene pressed Assange to verify the theory that the 20,000 leaked emails from the Democratic National Committee that Wikileaks published came from Russia. “Did those hacks that Wikileaks released, did those emails come from Russia?” Greene asked. “Well we don’t comment as to our sources,” Assange replied. He remains confined in the Ecuadorian embassy in London where he has lived since 2012, despite a U.N. panel’s ruling that he has been “arbitrarily detained.”
